hmmm ok
Is'tn the block shorter?

 

that was my orig thought sem..

 

hmmm I want to try it out.
I got a D15 in my shed and a D16 crank and rod's
But i don't want it not to be able to work though.
Does the D16 crank have a shorter stroke? if so it would be able to work

 

ATTENTION! I dont the crank is the problem, its the block, I came across a similar problem I bought a je piston/eagle rods combo for a b18c5 hoping it would have bveen a step up for my b16, the rods where too long, so I ask around about changing the crank, the answer was no way. b18 block is higher than b16. so its the same relation with d15 and d16

 

not necessarily.

The D15 has 134mm rods, 84.5 mm stroke, and a 75mm bore.
The D16 has 137.?mm rods, 90.0mm strok and a 75mm bore. These are pretty close, there are a few 1/1000s here and there.

So if the D16 has roughly 6mm longer stroke, that would equal 3mm at the top and 3mm at the bottom, And a 3mm longer rod- that would equal the same lower position as a d15 and a 6mm higher than D15 position at the top of the stroke. Right? So yeah, maybe the blocks are different. I've got a few of each at home, I'll check it out.

 

yeah I thought so no fitty

 

D16 cranks have way larger journals than D15's so swapping in a crank is out of the question.

I am pretty sure both blocks have the same deck height. I have always asked myself this question too, would putting D16 rods in a d15 work? yes, they are longer.. but will there be interference? I'm sure someone has tried this..

hmmm if you could at least get a 3mm blockplate it might work

 

nope not going to work without customization

 

d15 sucks ***
